Unfortunately, in North America, medicine is extremely drug-oriented, and the American and Canadian Medical Associations have strong ties to pharmaceutical companies. It is no surprise that doctors, who are trained to use drugs, are hesitant to study herbs. Herbalist Michael Moore, author of Medicinal Plants of the Pacific Northwest, sums it up well: "I have known perfectly intelligent physicians whose sole regularly used reference manuals were the Physician's Desk Reference and Goodman and Gillman, both of which are drug manuals. Their patients have come to expect, and receive, prescriptions as their only therapy."
Obviously, doctors are not the only ones who consider drugs their first option for treatment. The pharmaceutical companies are also not likely to change the way they do business. They can easily spend anywhere from $50 million to $100 million, mostly for safety testing, when submitting a new drug application to the FDA for approval. These companies are willing to pay that much because a new drug can reap incredible profits for the firm that holds the patent rights. Herbs, however, are available to anyone with a garden, and they cannot be patented. Drug companies are understandably reluctant to invest in a product that their competitors can pick up after the research is done. The result is that few herbal remedies are manufactured commercially, and drug use (especially use of specific brands of drugs) is encouraged.
